US Dollar Index (DXY) approaches a key resistance area above 98.65

• The US Dollar Index found resistance at the top of the monthly channel, at 98.65.
• A cautious market mood keeps supporting the USD, but bullish momentum has eased.
• US data, due later today, might increase bearish pressure on the Greenback.

The Dollar is moving higher for the second consecutive day on Wednesday, but USD bulls are showing signs of hesitation -the large wicks in the 4-hour candle- as price action approaches a cluster of resistances between 98.65 and 98.85.

The fundamental background remains favourable, with investors wary of risk amid a global sell-off in government bonds. Nevertheless, US data due later today is likely to show further evidence that the US economy is losing, which might shift the focus back to the Fed and dent the US Dollar's rally.

Technical Analysis: Testing trendline resistance at 98.65

The US Dollar has reached the top of the descending channel that contained price action during the last month, at 98.60, which has resisted the first attempt. Above here, the August 27 and 21 highs, at 98.75 and 98.85, respectively, are likely to offer some resistance ahead of the August 5 high, at 99.10.

The 4-hour Relative Strength Index (RSI) is turning lower, although still within bullish territory. The MACD shows a dwindling bullish momentum. A deeper reversal from current levels is likely to find support at the intraday level of 98.05.

Further down, the August 22 and September 1 lows, at 97.55, are likely to be tested before the trendline support, now at the 97.35 area.
